Question

For the following example, identify the following:

Answer 1

Answer: Option (A) is the correct answer.

Explanation:

According to the Gibb's free energy conditions:

     If $\Delta G$ < 0, then reaction is spontaneous.

     If $\Delta G$ > 0, then reaction is non-spontaneous.

      If $\Delta G$ = 0, then reaction is equilibrium.

Since, the given reaction is $F_{2}(l) \rightarrow F_{2}(g)$. It denotes that liquid state of fluorine is changing into gaseous state. And, the boiling point of fluorine is very low.

Therefore, at low and high temperature fluorine is a gas. Hence, the reaction is spontaneous in nature.

Thus, we can conclude that the statement at low temperature, the reaction is spontaneous and $\Delta G$ < 0 and at high temperature, the reaction is spontaneous and $\Delta G$ < 0, is correct.
